Different application scenarios (for example: time reminding, receiving information, alarm clock, games, etc.) can also correspond to different vibration feedback effects. Different user operations (for example: single click, double click, long press, etc.) can also correspond to different vibration feedback effects. The vibration feedback effect can also support customization.

As shown in FIG. 2, a motor vibration system in an electronic device is exemplarily shown. The system includes a battery power supply system 201, a motor drive chip 202, a processor 203, and a motor 191.

Among them, the battery power supply system 201 is used to supply power to the entire electronic device including the motor. It may include a power management module 141, a battery 142, a charging management module 140, and so on.

The motor driving chip 202 is used to control the power of the driving motor signal. It can be an independent chip, including a power amplifier (PA), a smart power amplifier (Smart PA), and so on. It can also be integrated in the processor 110 in FIG. 1, and in some implementations of the embodiments of the present application, the motor vibration waveform is generated and stored.

The motor 191 is used to generate vibrations and convert electrical signals into mechanical vibrations.

The processor 203 is used for control processing of the electronic device, including processing for controlling the vibration of the motor. It may be the processor 110 shown in FIG. 1 or may be integrated in the processor 110 in FIG. 1. 2 exemplarily shows that the processor 203 includes a battery management software system 204 and a motor software system 205. The storage of the motor vibration waveform and the generation of the motor vibration waveform may be supported by the motor software system 205 or the motor drive chip 202, which is not specifically limited in the embodiment of the present application.

Among them, the battery management software system 204 is used to detect and manage the status of the battery system, including the current battery temperature, power level, aging degree, internal resistance, supported voltage, current, and so on.

The motor software system 205 is used to receive the motor vibration request, and transmit the converted motor vibration request to the motor driving chip 202, and then drive the motor 191 to vibrate.

In some implementations of the embodiments of the present application, the motor software system 205 can obtain information such as battery temperature, battery power, and power supply capability from the battery management software system 204. It is also possible to directly obtain raw data from the sensor module 180 and hardware detection points as shown in FIG. 1, and obtain information such as battery temperature and power supply capacity through algorithm calculation.

In some implementations of the embodiments of the present application, the battery management software system 204 can monitor the power and temperature of the battery 142 in real time, and can obtain current power supply capacity data of the battery 142, such as the maximum output current of the battery 142 under current conditions. In this way, the electronic device 100 can determine whether the vibration power consumption of the motor 191 needs to be reduced according to the power supply capacity of the battery 142. If the power supply capacity of the battery 142 is lower than a certain threshold, the vibration power consumption of the motor 191 needs to be reduced to prevent the electronic device 100 from powering down abnormally.

The battery management software system monitors the battery power supply capacity in real time, and calculates the corresponding battery power supply capacity based on changes in factors that affect the battery power supply capacity. Factors that affect the power supply capacity of the battery include: battery temperature, battery power, battery aging, etc. Among them, the influencing factors of battery aging can be the number of charging and discharging, the length of use, and so on. The battery aging influencing factors have a long influence period on the battery power supply capability. The embodiment of the present application mainly considers the influence of the battery temperature and the battery power on the battery power supply capability.

Refer to Table 1 below, for example, a table of the power supply capability of the battery 142 under different battery temperature and battery power conditions for a certain type of battery listed. It can be seen from Table 1 that under the same battery temperature, different battery power levels correspond to different battery functions, and under the same battery power level, different battery temperatures correspond to different battery power supply capabilities. Therefore, it is necessary to synthesize the battery temperature and battery power to know the power supply capability of the battery 142 under the current conditions, and to determine whether it is necessary to reduce the power consumption of the application (such as the motor 191) at this time.

Battery temperature (℃)	-5	-5	-5	-10	-10	-10	-20	-20
battery power	30%	20%	10%	50%	30%	20%	50%	20%

The motor software system inputs the motor vibration waveform into the motor drive chip, and then drives the motor to vibrate according to the motor vibration waveform. Different motor vibration waveforms can bring different vibration experiences to users. As shown in Figure 3, if the motor vibration waveform is relatively smooth, such as waveform 1 and waveform 2, when the mobile phone vibrates, the vibration of the mobile phone may be more gentle and last longer. , The user’s vibration experience will be more peaceful; if the motor’s vibration waveform is sharper like waveform 3, when the mobile phone vibrates, the vibration of the mobile phone may be stronger and the duration is shorter, and the user will get a more exciting vibration experience. Among them, motor vibration waveforms with similar shapes can bring a similar vibration experience to users, but the intensity of the vibration sensation that the user can feel will be different if the amount of vibration is different. For example, the vibration waveforms of two motors are relatively smooth, one of which has a vibration of 0.8g and the other has a vibration of 0.4g. Then the user will feel that the vibration of the larger vibration waveform has a stronger vibration. .

In some implementations, different motor vibration waveforms can be designed in advance, and these motor vibration waveforms can be saved to the motor waveform library. In the motor waveform library, the motor vibration waveforms can be numbered, so that the corresponding motor vibration waveforms can be called by subsequently calling different motor vibration waveform numbers.

Optionally, in some implementation manners of the embodiments of the present application, the vibration waveforms in the motor waveform library are classified according to conditions such as user vibration experience. As shown in Figure 4, four different partial motor vibration waveforms containing peak waveforms are exemplarily given. These four vibration waveforms can be divided into two groups according to the user's vibration experience. The first group is that the user's vibration experience is relatively gentle. The vibration waveform of Figure 4 (a) and Figure 4 (b) two waveforms. The two waveforms are similar in shape but different in vibration amount. Although the user can obtain a similar vibration experience, the vibration intensity is different. The second group of vibration waveforms that are more stimulating for the user's vibration experience includes two waveforms (c) in FIG. 4 and (d) in FIG. 4, and the two waveforms are similar in shape, and the user can obtain a vibration with a similar vibration experience.

Different motor vibration waveforms bring different vibration experience to users, and mobile phone manufacturers pre-configure the above-mentioned motor waveform library. In the development process, mobile phone manufacturers select motor vibration waveforms from the motor waveform library for unused applications or gestures; third-party application developers select motor vibration waveforms from the motor waveform library during the third-party application development process. The pre-configured motor vibration waveform conditions corresponding to the unused applications or gestures are stored in the internal memory 121 of the electronic device 100. There are two ways to store the motor waveform: one is to store the motor vibration waveform data, that is, to store the motor vibration waveform in the internal memory 121, and directly call the corresponding motor vibration waveform when needed. The other is to store motor vibration waveform parameters, such as input voltage characteristic value, input current characteristic value and so on. That is, the motor vibration waveform parameters such as the input voltage characteristic value and the input current characteristic value are stored in the internal memory 121, the corresponding motor vibration waveform parameters are called when necessary, and the motor vibration waveform data is generated according to the motor vibration waveform parameters. In practical applications, when the mobile phone detects certain operations of the user, the mobile phone drive motor vibrates according to different vibration waveforms, so that the user can directly judge whether the current operation is correct according to the vibration experience. For example, click the corresponding waveform 1, double-click the corresponding waveform 2, and press and hold the corresponding waveform 3. Wave 1, Wave 2, and Wave 3 are motor vibration waveforms with different waveforms, and the vibration experience is quite different. After double-clicking, the user can sense whether the current vibration waveform is vibration waveform 2 according to the vibration experience, and then determine whether the phone detects the double-click operation If a detection error occurs, such as a single-click operation detected by the mobile phone, and the drive motor vibrates according to waveform 1, the user can perceive the abnormal operation according to the vibration experience and perform the single-click operation again. For another example, set different vibration modes (different vibration waveforms) for short messages and phone calls. When the mobile phone receives short messages or incoming calls, users can learn that the current vibration alert is new according to the different vibration experience without having to check the phone screen. Message or new call.

In some implementations of the embodiments of the present application, the vibration power consumption of the motor 191 can be reduced to adapt to scenarios where the battery 142 has a low load capacity, such as scenarios where the battery temperature is low and/or the battery power is low. Specifically, a vibration waveform with lower power consumption or a method of lowering the input voltage can be used to reduce the instantaneous vibration peak current generated when the motor 191 vibrates, thereby effectively preventing the battery 142 from being overloaded and losing power.

Generally, the smaller the amplitude of the motor vibration waveform, the smaller the voltage and current values, and the lower the power consumption. As shown in FIG. 3, the motor vibration waveform generated by the change of input voltage or current with time is exemplarily given. For example, waveform 1 and waveform 2 are two motor vibration waveforms with similar vibration experience for users. Waveform 2 has a smaller amplitude than waveform 1. That is, the vibration current of waveform 2 is smaller than the vibration current of waveform 1, and the power consumption of waveform 2 is lower than that of waveform 1. The power consumption is low. In this way, if the motor vibration waveform corresponding to a certain application of the mobile phone is waveform 1, when the mobile phone is in a scene with low load capacity and needs to select a vibration waveform with similar user vibration experience and less power consumption, the motor software system can select waveform 2 Input to the motor drive chip, and the drive motor vibrates according to waveform 2.

An embodiment of the application provides a motor vibration control method. As shown in Figure 5, the method may include the following steps:

S101. The mobile phone sends a motor vibration request.

In a possible implementation, when the mobile phone receives a reminder, such as an incoming call signal or a short message signal, the motor needs to vibrate to prompt the user, or when the mobile phone detects some operation of the user, it needs to perform touch vibration feedback to the user. At this time, the mobile phone sends a motor vibration request to the motor software system 205, and then drives the motor to vibrate. During the processing of the motor vibration request, the motor vibration waveform needs to be determined. At this time, the mobile phone will query the current battery status to match the corresponding motor vibration waveform or input voltage.

It should be noted that in this embodiment of the application, when the motor software system 205 receives a motor vibration request (the motor vibration waveform can be statically stored or dynamically loaded), it determines the required motor vibration waveform and issues the vibration command To the motor drive chip 202, the motor 191 is driven to vibrate.

S102. The mobile phone queries the battery status.

In a possible implementation manner, referring to FIG. 2, the mobile phone can query the current battery status from the battery power supply system 201 or the battery management software system 204. The battery status includes battery temperature, or battery temperature and battery power, or battery power supply capability. The battery status is used to subsequently determine whether it is necessary to reduce the power consumption of motor vibration. When the motor vibration power consumption needs to be reduced, the motor vibration parameters that need to be switched can be determined according to the current battery state data. The motor vibration parameter may include a motor vibration waveform or a motor vibration wave input voltage. It is understandable that the motor vibration waveform in the motor waveform library has a number. When the motor vibration parameter needs to be switched to the motor vibration waveform, the motor vibration parameter is the motor vibration waveform number. Call the motor vibration waveform number to call the corresponding low Power consumption motor vibration waveform.

S103. The mobile phone determines whether the motor vibration power consumption needs to be reduced. If yes, step S104 is executed to switch the vibration parameter of the low power consumption motor. If not, execute step S105, that is, continue to use the current motor vibration parameters to drive the motor to vibrate.

In a possible implementation, set the preset condition, when the battery status meets the preset condition, it is judged that the motor needs to be driven with low power vibration, so as to prevent the momentary peak current of the high power motor vibration from being higher than the battery power supply. The current causes the phone to shut down abnormally. Among them, the preset condition is: the battery power supply capacity is lower than the first threshold, or the current battery temperature is lower than the second threshold, or the current battery temperature & battery power is lower than the third threshold array. The first threshold, the second threshold, and the third threshold can be obtained according to battery modeling data, test data, and empirical data, and are pre-configured in terminals such as mobile phones. The mobile phone can determine whether it is currently necessary to drive the motor to vibrate with low power consumption according to the battery state parameter, the first threshold, the second threshold, and the third threshold. If it is necessary to drive the motor to vibrate with low power consumption, the mobile phone needs to switch the motor vibration parameters to drive the motor to vibrate with low power consumption; if low power processing is not required, the mobile phone can continue to drive the motor to vibrate according to the current motor vibration parameters.

S104. The mobile phone switches the motor vibration parameters.

By switching the motor vibration parameters, the instantaneous peak current generated when the motor vibrates is reduced, thereby reducing the power consumption of the motor vibration and preventing the battery from overloading. Among them, switching the motor vibration parameters includes the following methods:

method one:

In a possible implementation, according to the power supply capacity of the mobile phone, the low-power vibration waveform is switched to drive the motor to vibrate. For example, different power supply capacity levels can be divided according to the battery power supply capacity, such as 1A-1.1A, 1.1A-1.2A Wait. Choose a vibration waveform whose peak current is less than the maximum power supply current of the mobile phone (corresponding to the lower limit of the power supply capacity gear) to effectively reduce the vibration power consumption of the motor. Among them, the power supply capacity of the mobile phone can be obtained according to the battery temperature and battery power, or the power supply capacity value can be directly obtained by the battery management software system, which mainly includes the maximum power supply current value of the mobile phone.

In order to ensure the user's vibration experience, when the battery load capacity of the mobile phone is low and low-power waveforms need to be switched, the mobile phone can switch the vibration to experience similar low-power waveforms for the user. As shown in Table 2 below, four waveforms No. 36-39 with similar waveforms in the above-mentioned motor waveform library and a user's vibration experience are exemplarily given, that is, these four waveforms belong to the same classification group. Table 2 also includes waveform No. 44, which belongs to another group of low-power waveforms, which is different from the vibration experience of waveforms 36-39. In order to unify the metric and ensure that the vibration peak current under the same voltage condition is obtained, the voltage needs to be normalized. Table 2 below shows the vibration amount and vibration peak current of different motor vibration waveforms when the voltage is normalized to 3.8V.

Table 2

Optionally, when the battery load capacity is reduced and a certain application or gesture requires vibration feedback, you can select the vibration waveform vibration experience corresponding to the operation of the application or gesture in the pre-configured motor waveform library according to the current battery power supply capacity Similar low-power waveforms. For example, the original motor vibration waveform is No. 36, when the battery load capacity is reduced, the motor vibration waveform can be switched to No. 37.

Optionally, the battery temperature and battery power will affect the battery power supply capability. Therefore, the vibration waveform of the motor available under the current temperature and power condition can be selected according to the battery power supply capacity and the motor vibration peak current, that is, the vibration peak current of the selected vibration waveform is lower than the power supply capacity of the battery, so that the current power supply current of the battery meets Motor vibration is required, without causing abnormal cell phone battery overload.

For example, according to Table 1 and Table 2, Table 3 is obtained. The mobile phone judges the current battery power supply capacity according to the current battery temperature and battery power, and then matches the corresponding low-power motor vibration wave waveform according to the battery power supply capacity to drive the motor to vibrate.

Optional motor vibration wave	38, 39	38, 39	39	38, 39	38, 39	39	39	39

For another example, the corresponding relationship between the battery temperature and battery power and the optional motor vibration waveform is pre-configured in the mobile phone, and then see Table 4 below. The mobile phone can directly match the corresponding low-power motor vibration waveform according to the current battery temperature and battery power. The drive motor vibrates.

Optional motor vibration wave	38, 39	38, 39	39	38, 39	38, 39	39	39	39

For another example, the corresponding relationship between the battery temperature and the optional motor vibration waveform is pre-configured in the mobile phone. See Table 5 below. The mobile phone can directly match the corresponding low-power motor vibration waveform according to the current battery temperature to drive the motor to vibrate.

table 5

Battery temperature (℃)	-5	-10	-15	-20
Optional motor vibration wave	38	38	39	39

For another example, when the mobile phone can directly obtain the battery power supply capability, refer to Table 6 below. The mobile phone can directly match the corresponding low-power motor vibration wave waveform according to the current battery power supply capability to drive the motor to vibrate.

Table 6

Power supply capacity (A)	1.5	1.2	0.95	1.4	1.26	0.94	0.78	0.568
Optional motor vibration wave	38, 39	38, 39	39	38, 39	38, 39	39	39	39

Optionally, when there are multiple selectable motor vibration waveforms, the multiple selectable motor vibration waveforms can be selected according to the actual experience requirements of the user. For example, among the waveforms of similar vibration experience, the corresponding waveform can be selected according to the magnitude of the vibration, and a large amount of vibration will also have a stronger sense of vibration on the user. Refer to Table 3. When the current battery temperature is -5°C and the battery capacity is 30%, there are two possible vibration waveforms, No. 38 and No. 39. Exemplarily, a motor vibration waveform with a larger vibration amount can be selected, and the user can obtain a vibration experience with a greater vibration sense. For example, select No. 38 vibration waveform to drive the motor to vibrate. Or, if the user is in a noisy environment (for example, the user is shopping), see Table 2, you can select a vibration waveform No. 38 with a large amount of vibration to drive the motor to vibrate, so that the user can quickly perceive the vibration. Or, if the user is in a relatively quiet environment (for example, the user is reading a book in the library), see Table 2, the motor can select a vibration waveform No. 39 with a small amount of vibration to achieve vibration, so that the user can perceive the vibration, but not Will affect other readers.

Optionally, a set of general low-power motor vibration waveforms can be established in the motor waveform library. Refer to Table 6 below. The general low-power motor vibration waveform group includes No. 90-94 low-power motor vibration waveforms. The battery power supply capacity is divided into certain intervals. Each interval corresponds to a waveform in the general low-power waveform group. When the mobile phone selects a waveform with a similar user vibration experience in the motor waveform library, the corresponding waveform cannot be matched. , The mobile phone can select the general low-power waveform corresponding to the lower limit of the power supply capacity in the current battery power supply capacity greater than or equal to Table 4, so as to switch the low-power waveform and prevent battery overload. For example, the current battery power supply capacity is 0.94A, which fails to match the vibration waveform of a low-power motor with a similar user vibration experience to the current motor vibration waveform. At this time, you can refer to Table 7 below, 0.94A>0.7A, select the 91st motor vibration waveform to drive the motor to vibrate.

Table 7

Battery temperature (℃)	-25	-20	-5	-5	-5
battery power(%)	20	40	15	20	30
Lower limit of power supply capacity (A)	0.3	0.7	1	1.2	1.5
Optional motor vibration waveform	90	91	92	93	94

It should be noted that the above-mentioned Table 1 and Table 2 are only exemplary giving some battery state conditions and some motor vibration wave parameters. From this, it can be understood that Table 3, Table 4, and Table 5 should also include more battery state conditions and corresponding optional motor vibration waveforms. And the above Table 2, Table 3, Table 4, Table 5 and Table 6 are all when the voltage is normalized to 3.8V, determine the vibration peak current, and then select the optional vibration wave model. The purpose of the normalization of the voltage is to unify the metric to ensure that the vibration peak current under the same voltage condition is obtained. The normalized voltage may also be other values, such as 4.2V, etc., which is not specifically limited in the embodiment of the present application.

Further, in the above Table 3, Table 4, Table 5 and Table 6, in the process of selecting the optional motor vibration waveform, only the peak motor vibration current needs to be less than the power supply capacity of the battery. It is understandable that the battery also needs to be a mobile phone Other components in the power supply, therefore, a preset threshold can be set. When the current difference between the peak motor vibration current and the battery power supply capacity is greater than the preset threshold, the corresponding vibration waveform is an optional motor vibration waveform. The preset threshold can be For the empirical data obtained in the experiment, the embodiments of this application do not make specific limitations.

In this way, as shown in Table 3, Table 4, Table 5, and Table 6, a table of correspondences between battery temperature, battery power, power supply capacity, and optional vibration wave models is established and stored in the memory of the mobile phone. When the mobile phone determines that the current motor needs low-power vibration, it can use the corresponding table to match the user's vibration experience with the corresponding optional motor vibration waveform.

Way two:

In a possible implementation manner, the input voltage for driving the motor to vibrate is changed to reduce the power consumption when the motor vibrates. For example, the input voltage that can currently be provided to drive the motor vibration can be obtained according to the power supply capacity (power supply current) of the battery. Exemplarily, the formula v=k*i*(V/I) can be used to establish the peak value relationship between voltage and current, so as to obtain the corresponding low-power input voltage. Among them, V represents the peak input voltage of the original motor vibration waveform; I represents the power supply current of the original motor vibration waveform; v represents the low power peak input voltage of the motor vibration waveform required under the current battery condition; i represents the current battery powering the motor Current capacity; k represents the motor coefficient, which is related to motor specifications and motor design systems. The empirical k values measured by different motor specifications and motor design systems are different. Exemplarily, when k=1, v/i=V/I can be obtained from the above formula, that is, the current input voltage for realizing motor vibration can be obtained, and the input voltage is the peak voltage of the motor vibration waveform. The compression ratio is calculated based on the peak voltage and the peak voltage of the current motor vibration waveform, and the current motor vibration waveform is compressed in equal proportions according to the ratio to obtain the switched motor vibration waveform, which effectively reduces the motor vibration power consumption.

Optionally, the above-mentioned proportionally compressed motor vibration waveform can be stored in the motor waveform library in the above mode 1, and furthermore, when the motor vibration waveform is needed again later, the motor vibration waveform can be directly called without having to do it again. Calculation.

It should be noted that the calculation of the input voltage of the motor vibration waveform can also be related to the specific motor model modeling. When a mobile phone manufacturer configures a motor for a mobile phone, it will perform modeling training verification on the parameters that affect the quality of the motor, and select the better parameters to control the quality of the motor. Motors of different models and qualities will have deviations in the realization of the input voltage. After the manufacturer uses the motor model to configure the motor for the mobile phone, the mobile phone can obtain the input voltage according to the above formula, without having to consider the influence of different motor models on the input voltage.

In this way, when the load capacity of the mobile phone is reduced and the motor needs to be changed, the motor waveform library can be pre-configured in the mobile phone according to the battery power supply capacity, or the battery temperature and battery power. The optional low-power motor with similar user vibration experience Vibration waveform. If the optional motor vibration waveform cannot be matched in the motor waveform library, then the above formula can also be used to determine the input voltage that the current battery state can provide to the motor, so that the battery can provide the proportionally compressed input voltage to realize the motor The low-power vibration. Or, when the optional user vibration experience similar motor vibration waveform cannot be matched in the motor waveform library, the general low-power motor vibration waveform that meets the current power supply capacity can be matched to reduce the motor vibration power consumption and prevent mobile phones. Power off abnormally.

S105. The mobile phone drive motor vibrates.

In a possible implementation, when the mobile phone determines that the current battery state can meet the current motor vibration condition in step S103, that is, when low-power vibration is not necessary, step S104 is not necessary, and step S105 is executed directly. The mobile phone uses the current motor to vibrate. The parameter drives the motor to vibrate.

In a possible implementation manner, after the motor software system is matched to the above-mentioned switched low-power motor vibration parameters, the motor is driven to vibrate according to the vibration parameters to provide vibration feedback to the user, so as to realize the motor under the condition of low battery load capacity. vibration.

In yet another possible implementation manner, a large capacitor device can be added to the motor to filter the vibration peak of the vibration waveform of the motor to achieve smooth peak current. Even if the motor does not generate an increased instantaneous current when it vibrates, it will not exceed the power supply capacity of the battery and overload the battery. Under the condition of low battery loading capacity, the vibration function of the mobile phone can also be ensured without causing abnormal power-down and shutdown of the mobile phone caused by vibration.

In another possible implementation, when the mobile phone determines that the motor needs low-power vibration in step S103, that is, when the mobile phone determines that the current scene is a scene with a low load capacity of the mobile phone, the motor can be made to vibrate in the output voltage of the mobile phone battery. When using the peak value of the voltage and high power consumption applications, the peak value of the voltage is used to achieve the peak supply. That is, it will prevent the motor vibration waveform from reaching the peak while running high power consumption applications, resulting in excessive transient current and battery overload and power down. Exemplarily, when a mobile phone takes a photo, the instantaneous peak voltage is high at the moment the shutter is pressed to take a photo. At this time, if there is an incoming call or a short message to remind the vibration, the peak value of the motor vibration and the peak value of the photographing voltage can be separated in time. Ensure that the current supply capacity of the battery state is sufficient to achieve the vibration of the current motor vibration waveform.

It can be seen that the motor vibration control method provided by the present application can dynamically adjust the motor vibration power consumption by switching the low-power motor vibration waveform or changing the motor vibration waveform input voltage in a scenario where the battery load capacity is low. The low-power motor vibrates without causing the phone to shut down abnormally. In order to improve the prior art, when the mobile phone is in a scene with low battery loading capacity, the motor vibration function is disabled, which makes the user experience poor.
